It has only two which are 2 and 17 because 1 is not considered as a prime factor
it is 2 and 3
Prime factorizations are expressions of numbers as products of prime factors. The prime factorization of 30 is 2 x 3 x 5.
Dumb...its 3 and 3...
2 x 3.
3*5*5 = 75
The prime factors are: 3 x 5 x 5
Taken individually, 1, 2, 3, 5 and 7 don't have prime factorizations. That leaves2 x 2 = 42 x 3 = 62 x 2 x 2 = 83 x 3 = 92 x 5 = 10Collectively, 28 x 34 x 52 x 7 = 3,628,800
3 x 19 = 57
3 x 3 x 59 = 531
3 x 3 x 59 = 531
378 = 2 * 3 * 3 * 3 * 7
3 and 19 are the prime factors of 57 3 times 19 = 57
